once pvp is back on, can these only work with PCs facing you in combat?

i know it's a bit OOC to consider PCs differently than NPCs, but let's face it, i'd like to use null gravity/ripple/etc on enemies during invasions and i know everyone won't be in my group as i cast it.

i'm also sure a few mages would love to use area attack spells.

i'd really just like the area spells to harm PCs that are facing me in combat.

is that going to be possible? heck, for all i know that's already the plan._________________A bright-eyed Thekko Ku Kalla dressed in a dapper sailor suit takes to flight and careers through the air toward the Modan Kucho and slams into him!

When we have an ES that supports it, I'll probably do something like this. It will curtail the power of the spell a bit in terms of PvP, but I think it would boost the usability of the spell outside of PvP quite a bit._________________"Wise men talk because they have something to say; fools, because they have to say something." -- Plato
